a lot of people have given very thorough explanations of why pfof is not an evil thing in this thread. i suppose you're free to believe your own narrative, if you want.
My only point is that the narrative of Robinhood is completely backwards. Far from the “stealing from the rich to give to the poor” backstory from which the name comes from, all they’ve done is encourage hordes of unsuspecting sheep to venture deep into the wolves’ den.
PFOF may not be evil, but Robinhood certainly is. The fact that their customers’ orders are of such high value makes it abundantly clear who the moneyed players think losers at the table are. Anyone paying attention understands that Robinhood’s product is a continuous flow of suckers to their paying customers. Trading on Robinhood is an implicit bet with apparently quite poor odds that you’re not one of those suckers.
That doesn’t mean you’re better off trading on some other platform. It means they're goading you into playing the wrong game in which entities with billions at stake are so convinced you will lose they’re happy to pay for the privilege of sitting down at the table with you. The real lesson is that you should be playing a different game than the one Robinhood is promoting.
